Itwi-ll be seen that the upper end or; rather the top of the doorisprovidedwith hangers 10 which operate on a traclnllext-mdirtg-01 th orpor io ol helen'sth Qi h ihQ/US. e ing t r the fre snt en 3"? the dooandcon- Briefly stated an importantobject of this invention istop-rovi-de I agrain-fcar .{door st t ting esuppe tins @ni ans l th 10It will he understood' that any suitable 11 3 1311 113) employed foslideb y un ingthei door.

The door frame consistsof:a-U-shaped member haVingw-a pair ofstiles, theinner sides of which are provided with grooves 15 for the reception-ofthe edge portio'nsi of; upper and lower panels 16,and' 17 respec:-tiv-ely; When the ,panels 16 and 17 are in their normal positions theyoverlap about six inches as illustrated in fianch there .ioiz have ubsant al ysta tish lc n as wi h each (other.

The gears 21 are mounted upon shafts 22Qill'lfld hy a cross har or striP223. ,ItHyvill' begsee'n by: referenceto 5 and A 7g that the gears 21 a e gaged "hy cgears 25 and .26, ithegear 25 being. mounted npon,ashaft. 27 hile the gear 26' is .mountednponashaft 2'8. The shaft-Q? may he provided ithasq ared or flat sid'edsocket for. the. receptionof A the attaching portion of crank 3.0 bymeans ofhioh the gfearsQl niay .he turned for raising and lowering. thelower panel ,17.

It is! believed: to be obvious that. the manual turning of the crankwill result-ineithenthe up or down n ove nent on the lower; pal-101,17.The enter portions, of the sha'fts are jcnaged by washers. 31mhich holdthe shafts against endwise, noyen ent and these Avash ersfareconneetedto the shafts by machine screws 3 L or other.suitahlen eans;vMachine screws or other suitable means nayv he employed to hold Washers35 iiiplace on} the shafts 27 and28.- This arrangement insures proper-IIl6S-l1.:0f all'of theqgearsnof theorganizati'on.

The cross-ineinher 23 -,m,ay;.be provided with one or more I paw-ls 37tosen'gage gin notches 38 in one or more oftheracksQO so as to; hold:the lower? panel in an adjusted position. ltlwill be seen that thepa -l37 issomewhat in the nature of-a lever pivoted intermediate the-endsthereof as shown at 54:05 andhaving; its rear :tenm-inal portigmaeic Theupper panel 16 is provided with brackets '50 adjacent Y the oppositeedges thereofand chains 51 are connected to these brackets and aretrained over pulleys 52. The chains 51 have their lower terminalportions trained about a drum '54 carried by the fixed cross bar 23.drum maybe said who apart of a shaft rotatably connected to the crossbar 2'3and having annular shoulders or washers56 and 58 by means ofwhich endwise' movement of the drum is prevented. The other-portion ofthe rotatable member 1 is provided with a squared socket 60 for thereception of the attaching portion of the crank so that the c "anlr maybe quickly connected to the drum forturning the same and lowering theupper panel. v j V n Fig. 5 illustrates that a ratchet'wheel '66maybesecured inany suitable manner on thedrum and is engaged by a pawl67 pivoted to the cross bar 23 and adaptedto hold the ratchet wheel andconsequently the drum in a set position. i i I The upper portion of thepanel 16 and the top rail of the door are provided with Kings 69 havinglongitudinally extending openings adapted for alinement for thereception ofa pin 70by means of which the panel may be locked in itsclosed position.

The door is, of course, movable into the easing or housing so as topermit the loading'or unloadingof the car orone or both of the panelsmay be moved to open position by the aid of the crank. It might bestated that when it is desired to start the unloading of the car thelower section is raised to allow some of the grain to be discharged andthereby relieve the pressure of the grain onthe door. WVhen suflieientgrain has been removed to relieve the pressure onthe door the dooris'moved to open position. When the door is returned to closed position itwill engagea stop i b The cross bar 23 may be provided with a hoodorhousing 79 toextendbver the gears and protect the same fromdust andatthe same time prevent the clothes or hands of the operator from comingin contact with the gears accidentally.

Figs. '8 and 9 illustrate that the "door casing may be provided with atwo-part sleeve to receive an arm 91 havingone end provided with aneccentric or cam 92 adapted to clamp the door in position. The arm 91 isprovided with a" radial lug 94 More specifically, the

positioned in a spiral slot 95 in the sleeve 90 so that when the arm 91isturned by the crank 96 on the outer end of' the same the armwillbemoved longitudinally. That is to say, the arm will be movedlongitudinally atthe same time it is turned so as to move ,the eccentriceither to operative or inoperative position according to the directionin which the same is manually turn ed.-

Having thus described the inventiom'what is claimed is:

1. A grain cardoor comprising a frame,

a cross bar carried by the frame, gears oarfor horizontal movement as aunit to completely open orcompletelyfclosed position.

2. A grain car door comprlsmg a frame, apan' oi: panels shdably carried.thereby,

frame and one of the panels whereby thepanel having the motiontransmitting mechanism may be raised and lowered,imeans carried bytheframeand the other panel for raising and lowering the other panel, andmeans whereby the frame and the said parts carried thereby may be movedas a unit to open position to completely expose the opening the door isadapted-toclose.

A grain-car door comprising aframe, panels slidably carried by said'frame and having their adjacent portions overlapped when the panels arein closed position, a cross bar connected tosaid frame and extendingacross the frame at the point where the panels overlap, motiontransmitting mech anism carried bysaid cross bar and one oil saidpanels, a second motion transmitting mechanism connected to said crossbar and the other panel, and means whereby the frame and the said partcarried thereby may be moved to open position to completely expose theopening thedoor is adaptedto close.

4. A grain car door comprising a frame havingits inner sides providedwith grooves,

panels extending into said grooves and having their adjacent portionsoverlapped, a cross bar connected toythe sides of said door f 'ame,gears carried by said cross bar, racks carriedby one of said 'panelsandengaged with certain of said gears, means whereby said gears may beturnedfor moving one of said panels vertically,rmanually controlledmeans for moving the-other panel vertically and means wherebythe frameand the said partscarried thereby may be moved to open position tocompletelyexpose the opening the door is adapted to close.

5. In a gram car, the combination of a 90 motion transmitting meanscarried by the loo a,

side wall having an opening, a door adapted to close said opening, asleeve extending through said side Wall and having a spiral slot, an armextending through saidsleeve and having a radial lug received in saidslot whereby the turning of the arm results in the longitudinal movementof the arm, and a cam arranged on the inner end of said arm and adaptedto engage saiddoor to hold the same in a set position. v

6. In a grain car, the combination of a side Wall having an opening, adoor adapted to close said opening, a sleeve extending through said sideWall and having a spiral slot an arm extending through said sleeve andhaving a radial lug received in said slot whereby the turning of the armresults 111 the longitudinal. movement of the arm, a cam tures.
